It's called grammar.

The worst part about reading ads on Craigslist is the complete lack of proper grammar, capitalization, and spelling in 90% of the ads. Well, technically, that's three things, but they all fit in the same category of being able to write at a high school graduate level. How the hell can a man expect to attract a female with a sentence like this: "Ok so im tired of finding girls who are either interested on nice cars, sex and.money, I need someone who I can actually call my gf, someone to talk on the phone till late , txt , spend time with on weekends or just take a random.trip to anywhere and take a long walk and just talk about anything." I don't understand. Is it that impossible to not stick in random periods or to actually properly place spaces? And the guy is my age. When that's what is available, is it any wonder that I am single and find it impossible to find a long-term partner? Is it so wrong to hold out for a man who has read, on his own accord, something other than the sports section of the local newspaper and is also straight?
